Was Texas a place where a law was passed that allowed employees to carry firearms in their vehicles at their work place?

it's a national trucking operation, many drivers carry weapons whether permitted or not given that a robbery could happen at any time and any place, having a gun seems to make many of them feel less vulnerable. If they feel they need their guns, they'll have them handy, legally or not.

Any comment I might make would probably be colored by my general impression of Texas. I'm still trying to figure out what Sheriff Hickman meant when he said the shooting was a retaliatory act. I don't think the Sheriff said it to excuse or justify the shooting, but I don't know for a fact that he didn't mean it that way.
